On day one an aeroplane (A1) lands at a remote airstrip. On day 61 another aeroplane (A2) lands on that same remote airstrip. The heat produced by aeroplane A1 defies physics and doesn't dissipate, it has magically hung around and is added to the heat produce by aeroplane A2. After twenty years and (let's be extravagant) 500 landings, the temperature at that remote airstrip has risen by the amount of heat from A1 + A2...A500.

Sheesh, that airstrip is probably really hot by now isn't it. No wonder the world is heating up :D

Addendum:

To show how sceptical "fake sceptics" are, and whether or not they check sources, compare the following comment from a WUWT reader...

...with the first paragraph of the BEST paper that Willis 'discusses'.

The Urban Heat Island (UHI) effect describes the observation that temperatures in a city are often higher than in its rural surroundings. London was the first urban heat island to be documented [1] but since
then many cities have been identified as urban heat islands [2-5]. A well-known example is Tokyo where the temperature has risen much more rapidly in the city than in nearby rural areas: Fujibe estimates excess warming of almost 2°C/100yr compared to the rest of Japan [6] The warming of Tokyo is dramatic when compared to a global average as seen in Figure 1. The UHI effect can be attributed to many physical differences between urban and rural areas, including absorption of
sunlight, increased heat storage of artificial surfaces, obstruction of re-radiation by buildings, absence of plant transpiration, differences in air circulation, and other phenomena [7].

New Look

G'day. HotWhopper is having a facelift. Do let me know if you find anything missing or broken.

When you read older articles on a desktop or notebook, you may find the sidebar moves down the page, instead of being on the side. That can happen with some older articles if your browser is not the full width of your computer screen. I am not planning to check every previous post, so if you come across something particularly annoying, send me an email and I'll fix it. Or you can add your thoughts to this feedback article.

You can use the menu up top to get to the blogroll or whatever it is you might be looking for on the sidebar.

All you need to know about WUWT

WUWT insider Willis Eschenbach tells you all you need to know about Anthony Watts and his blog, WattsUpWithThat (WUWT). As part of his scathing commentary, Wondering Willis accuses Anthony Watts of being clueless about the blog articles he posts. To paraphrase:

Even if Anthony had a year to analyze and dissect each piece...(he couldn't tell if it would)... stand the harsh light of public exposure.

Definition of Denier (Oxford): A person who denies something, especially someone who refuses to admit the truth of a concept or proposition that is supported by the majority of scientific or historical evidence.
‘a prominent denier of global warming’
‘a climate change denier’

Alternative definition: A former French coin, equal to one twelfth of a Sou, which was withdrawn in the 19th century. Oxford. (The denier has since resurfaced with reduced value.)
